HOUSING FOR TAPPE'I' AND ROCKER ARMS FOR INTERNAL COMBUSTION ENGINES MedMay 2. 192a FIG. .1

l l INVENTOR. f; Thomas P Cam Patented Apr. 28;, 1925..

UNITE sire THOMAS P. GAIN, OF "WICHITA, KANSAS.

Application filed May 2,

To aZZ whom it may cancer Be it known that I, THOMAS P. CAIN, a citizenof the United States, residing at l i ichita, in the county of Sedgwickand State of Kansas, have invented certain new and useful Improvementsin Housings for Tappet and Rocker Arms for Internal- Gombustion Engines,referencebeing had to the accompanying drawings, which form a part ofthis application.

My invention relates to housings for can posed operating parts ofinternal combustion engines.

The objects of my invention are as follows; i i

First. To provide a housing that will encase. the moving mechanisms thatare exposed on the engines, sheltering it from dust or other exposure.

Second. A housing that tends to muffle the noise of the engine. a

Third. A housing that supports and holds in place a fabric oilingdevice.

Fourth. A housing and simple to apply.

Referring to the drawings;

Fig. 1 is a top view of the housing.

Fig. 2 is a side elevation showing the cap made of; two parts and sidehousing assembled.

Fig. 3 is an end viewof Fig. 2.

Fig. 4 is a sectional view through the block and housing taken on lineA.-A in Fig. 5, looking in the direction of the arrows.

Fig. 5 is a sectional view of the housing,

showing its relative position on the engine.

1 is the cap covering the top of the engine in which is interposed afabric sheet 2, said sheet being saturated with oil tends to lubricatethe trunnions of rocker arm 3, said cap resting with one edge on theengine at a and on the opposite side resting on the housing 5 at B, saidhousing 5 has its been ing on the block 6 and is firmly attached to theblock by means of a bolt 7, engaging a plate D on the opposite sidethereof, said plate engaging with the walls of thecylin-- ders at E,enclosing the openings between said cylinders, and being spaced fromsaid block by means of a boss 8, and when ten sion is produced bytightening the bolt 7, the said housing 5 is held firmly to the block,the cap 1 is attached firmly in position by means of bolt 9, said boltscrewing into the rocker arm bracket at 10, functioning as binding meansto hold the rocker arm rod 192s. eel-m1 is. 636,123. r

11, firmly in place when the usual set screw that is used for thatpurpose is removed for convenience of attaching said bolt 9., The

said bolt 9 has a nut 19; by which means of a shoulder 14- and in saidhousing are To openings to accommodate for the adjusting rod fordistributor 15. said rod passing through the elongated slot 16, and at1? is a lltXttgOll openin through which passes the exhaust connection 18by the application of 7- my improved housing, the tappet 19, and rockerarms 20, and connecting rod 21 are protected from the dust which is sofreely discharged through the radiator by action of the fan and by thisprotection the said operative parts are kept in a clean condition, freefrom grit, preventing the bearings from wearing and failing to functionas they should and by supplying oil continously on the fabric sheet tothe pivot joints, eliminating the possibility of overlooking oiling ofsaid joints as must be done the ordinary way, by the use of the oilingcan, lubricating each joint separately, and the said sheet fittingclosely to the side walls of cap 1,

functions as a dust proof means for the rocker arm and all moving partsconnected thereto should the dust pass through the oiling apertures 13.

Such modifications may lies within the scope of the appended claims.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is;

In a housing for tappets and rocker arms 0 for internal combustionengines, a housing having its edges fitting closely to the outside wallsof the engine, said housing comprising two parts namely a cap and sidewall, said cap having apertures'functioning 105 as oil holes, aperturesin alignment with rocker bearings, bolts connected to said bearings andextending through last said apertures and having nuts screwed thereon asbinding means, the edges of said cap adapted to rest on the engine andon the side wall, a fabric sheet interposed Within held. in its properposition by 65 be employed as said cap and fitting closely to the sideWalls thereof, said fabric sheet being saturated With oil, said oilbeing poured through first said aperturefsaid oil saturated fabric sheetfunctions as dust proof means for the rocker arms of said engine, a sidewall engaging and covering that side of the engine on which the rockerarin connecting rods are positioned, bosses on sand side Walls I0engaging with the Walls of the cylinders as spacing means, an opening insaid side Wall to receive the exhaust pipe connection an open ingthrough which will pass the distributor adjusting rod, an anchor boltand plate to bind said side Wall firmly to the Walls of the engine, saidadapted to close the space between the two intermediate cylinders of theengine completing the housing.
